DTC P2716 Pressure Control Solenoid "D" Electrical
(Shift Solenoid Valve SLT)
CIRCUIT DESCRIPTION
See page DI-1073
DTC No. DTC Detection Condition Trouble Area
S Open or short in shift solenoid valve SLT circuit
Open or short is detected in shift solenoid valve SLT circuit for
P2716 S Shift solenoid valve SLT
1 second or more while driving (1-trip detection logic).
S ECM
MONITOR DESCRIPTION
When an open or short in the linear solenoid valve (SLT) circuit is detected, the ECM interprets this as a fault.
The ECM will turn on the MIL and store the DTC.
